Hi Guys,
We currently run OSPF across our POPs - redistributing connected + static
subnets.
So, provision a customer tail, and all POPs know about the new subnet....and
also if we statically route an additional subnet to a customer, all other POP's
are updated.
Our issue is if we need to run OSPF to the customer(eg if they have redundant
connections), and they require an additional subnet(So they advertise the
additional subnet back to us via OSPF), the only POP that is "aware" of the
advertised additional subnet is the one that has the OSPF session to the
customer - All our other POP's dont see this advertisement as it is within a
different OSPF process to our "Internal" OSPF process - Solution is to
redistribute ospf process(customer) in our "Internal" OSPF...but we also have
to use route-map/acl to ensure they dont potentially blackhole us(by
advertising something back to us that they shouldnt)....Is there a "better" way
to be doing this? As having to redistribute customer ospf/controlling that
redist with route-map/acl just doesnt seem like a "good" solution?(At the very
least, it's terrible to manage)
Thanks in advance for any suggestions.
